Hello @matsalo,

Please put the CSS below in Customizing > Custom CSS/JS > CSS Code:

.single-post #wrap .entry-content figure {
    margin: 1.5em auto;
    max-width: 700px;
}

Please read this link for more information about the CSS/JS code on the customizer: https://docs.oceanwp.org/article/354-add-custom-css-and-js-to-your-website.

Note: if you have any cache plugin or server cache(CDN / Browser Cache and Cookies and …), you need to clear its cache contents or disable them to see your changes.

Hope it helps,
Best Regards
